Does Houston have a problem?

The Houston Texans are 9-1 and sit atop the AFC standings. But their 43-37 overtime win over the Jacksonville Jaguars on Sunday certainly left something to be desired. Surrendering 34 points in regulation to the Jaguars? It begs a simple, yet important question: Is the Texans' defense good enough to get them to where they want to go?

Earlier in the season, teams were being bowled over by J.J. Watt, but as we explained last week, you can take him out of a game. And when you do, the Texans' defense doesn't pack quite the same punch.

Have teams figured out how to slow down Wade Phillips' defense? Or was Sunday just one of those games?

What went wrong?

So how did Jacksonville pick up so many points? It wasn't on the ground, where the Jaguars averaged just 3 yards per attempt. No, it happened in the air where Chad Henne came in and threw for 354 yards on 33 attempts while taking only one sack. The Texans' defense found itself attacked over the middle of the field, with Henne completing 6-of-9 passes for 237 yards on balls thrown between the numbers and 10-plus yards beyond the line of scrimmage.
